BACKGROUND

The current packaging devices for packaging display panels normally place the display panels in a same direction during packaging, the parts of the display panels having the driving circuit boards are stacked together at one side, and the parts of the display panels having the panel modules are stacked together at the other side.

The driving circuit boards of the two display panels are staggered with each other, to prevent the soft circuit board, such as the chip on film (COF) from standing against a pull. And, after multiple display panels are stacked together, two parts of the stacked display panels are at a same altitude, the height refers to the thickness of the stacked display panels, is not necessarily a physical height formed from the top to bottom.

Furthermore, the first direction is a direction from an opening of the box body to the bottom of the box body, the second direction is a direction from the bottom of the box body to the opening of the box body, the first direction and the second direction are interchangeable.

When packaging the display panels, the part of the display panel having the driving circuit board faces the bottom of the box body, the part of the another display panel having the driving circuit board faces the opening of the box body, and that cycle repeats until the box body is full-filled.

Two adjacent display panels are next to each other, while the driving circuit board and the panel module are staggered with each other, a height of an element located at the part of display panel having the driving circuit board is greater than a height of an element located at the part of the display panel having the display module, as such after the display panels are reversely stacked together, especially, there is an even number of display panels which are reversely stacked together, the thicknesses of two parts of the stacked display panels are almost the same, which can prevent the COF from standing against a pull and from being damaged which would be induced by the height of the part of the display panels having the driving circuit boards is greater than the height of the part of the display panels having the panel modules. Therefore, the yield rate of the stacked display panels can be improved. This kind of stack allows that two parts of the stacked display panels are almost at the same altitude, such that the loading quantity of the display panels in each packaging box can be improved to make a good use of the packaging box, and the cost is reduced.

When placing the display panels according to the above method, a first block of display panel is placed in the box with the driving circuit board towards the bottom of the box, that is, the driving circuit board faces downwards, then a second block of display panel is placed in the box with the display panel towards the opening of the box, that is, the driving circuit board faces upwards. Therefore, the driving circuit boards of the two adjacent display panels are staggered with each other. Or, the first block of display panel is placed in the box with the driving circuit board towards the opening of the box, then the second block of display panel is placed in the box with the display panel towards the bottom of the box. The present disclosure does not limit the order of placing the display panels.

A height of an element located at the part of display panel having the driving circuit board is different from a height of an element located at the part of the display panel having the display module. When packaging the display panels, if the display panels are placed in this same direction, which may cause thicknesses of two parts of the display panels (vertically placed) are inconsistency, and the COF of the display panel is prone to stand against a pull. The above problem can be avoided by reversely placing each two adjacent display panels.

Furthermore, the fixing elements 101 include a plurality of first protrusions 1011 and a plurality of second protrusions 1012, which are all located at an up end of the side wall, that is, the first protrusions 1011 and the second protrusions 1012 are all adjacent to the opening of the box body.

That is, two sides of one fixing element 101 can both be used for fixing element, as such the number of the fixing elements 101 can be reduced.

As the thickness of the driving circuit board substrate is different from the thickness of the panel module substrate, the thickness of the first protrusion 1011 is also different from the thickness of the second protrusion 1012.

In another exemplary embodiment, the fixing elements 101 can be the same (including the thickness), while, the fixing elements 101 cannot be reused when the fixing elements 101 are used for fixing the display panel.

Therefore, the yield rate of the stacked display panels can be improved. This kind of stack allows that two parts of the stacked display panels are almost at the same altitude, such that the loading quantity of the display panels in each packaging box can be improved to make a good use of the packaging box, and the cost is reduced.
